摘　　要：以硫酸铁、硫酸铝和凹凸棒土为原料,制备了凹凸棒土/聚合硫酸铁铝新型复合絮凝剂。通过单因素实验得到优化合成条件:凹凸棒土投加量487.5 mg,反应时间2 h,熟化时间19 h,盐基度15%,反应温度50℃。在此条件下制备的复合絮凝剂絮凝效果好,除浊率可达81.62%。A kind of novel flocculant attapulgite/polymerized ferric - aluminum sulfate （APFAS） was p using ferric sulfate, aluminum sulfate, and natural mineral attapulgite as raw material. The optimum preparing conditions, which were the amount of attapulgite 487.5 rag, reaction time 2 h, curing time 19 h, basicity 15%, and reaction temperature 50℃, were determined by single factor test. The flocculant prepared under the optimum conditions had good flocculating efficiency and the rate of removal turbidity was up to 81.62%.
